- The present invention relates to a linear compressor, more particularly, wherein an edge of a loop pipe, which is inserted into an outer exhale cover in order to discharge fluid in the outer exhale cover to the outside is inclined. The linear compressor is capable of preventing the edge of the loop pipe from clogging by an inner exhale cover, and of improving an assembling capacity and reliability.
- 2. Description of the Related Art
- Generally, a linear compressor is a machine to inhale, to compress, and to discharge fluid by linearly reciprocating a piston within a cylinder, by means of linear driving force of a linear motor.
-
FIG. 1 shows the linear compressor, based on the prior art, andFIG. 2 shows a structure of an exhale part of the linear compressor, based on the prior art. - In a
hermetic casing 2 of the linear compressor, according to the prior art comprises acylinder block 4 having thecylinder 3, and aback cover 6 having aninlet 5 are equipped. Thecylinder block 4 and theback cover 6 are upheld in thehermetic casing 2 by amain damper 7 and asubsidiary damper 8, so as to absorb a shock(seeFIG. 1 ). - The
linear motor 10 is disposed between thecylinder block 4 and theback cover 6, which generates driving force to compress fluid. - The
linear motor 10 is divided by a stationary part and a movable part. The stationary part includes anouter core 11, aninner core 12, and acoil 13 with a magnetic field. The movable part includes amagnet 14 that linearly reciprocates by magnetic force around thecoil 13, and amagnet frame 15 which themagnet 14 is fastened to. - The
piston 16 is mounted in thecylinder 3, which receives linear driving force from themagnet 14, linearly reciprocates, and compresses fluid within thecylinder 3. - In a rear of the
piston 16, aflange 17 is formed to be fixed to themagnet frame 15. Amain spring 18 is disposed between theflange 17 and thecylinder block 4, and asubsidiary spring 19 is disposed between theflange 17 and theback cover 6, so that thepiston 16 is elastically suspended. - The
piston 16 is in a shape of a cylinder, which is open at its rear. Aninhale passage 20 where fluid is entered is provided therein, and a plurality ofinhale ports 21 is provided in its front. - In a front of the
piston 16, there is aninhale valve 22 for opening and closing theinhale port 21. Fastened to thepiston 16 by a connection member, theinhale valve 22 gets elastically bended, depending on a pressure difference between the inside and the outside of theinhale port 21, thus opening and closing theinhale port 21. - The
exhale part 30 is formed in a front of a compression chamber C of thecylinder 3, where compressed fluid is discharged. - The
exhale part 30 includes aninner exhale cover 32 fixed to thecylinder block 4 and provided with anexhale hole 31, anexhale valve 34 suspended to theinner exhale cover 32 by anexhale spring 33, so as to open and close the compression chamber C of thecylinder 3, and anouter exhale cover 35 positioned at a regular interval from an outer surface of the inner exhale cover 32(seeFIG. 2 ). - The
outer exhale cover 35 has aconnection pipe 37 combined with aloop pipe 36 which discharges compressed fluid to the outside. - One end of the
loop pipe 36 is connected to theconnection pipe 37, and the other end penetrates thehermetic casing 2. To reduce a vibration and a noise occurred by discharging compressed fluid, a material is equipped at a predetermined position of the loop pipe. Otherwise, the loop pipe functions as the material by being rolled several times at a predetermined position or by being bended. - When assembling the
loop pipe 36, one end of theloop pipe 36 is inserted into theconnection pipe 37, and is fixed by welding. - The linear compressor having the conventional structure of the exhale part operates in the following sequence.
- In operation of the
linear motor 10, thepiston 16 has linearly reciprocating motion within thecylinder 3. Theinhale valve 22 is opened and closed, depending on the pressure difference between theinhale passage 20 of thepiston 16 and the compression chamber C. - When the pressure of the
inhale passage 20 of thepiston 16 is higher than that of the compression chamber C, theinhale valve 22 becomes opened, while elastically bended toward the compression chamber C. Fluid in theinhale passage 20 of thepiston 16 is flowed into the compression chamber C through theinhale port 21. - On the contrary, when the pressure of the compression chamber C is higher than that of the
inhale passage 20 of thepiston 16, the inhale valve becomes closed. Fluid in the compression chamber C is compressed by thepiston 16, makes theexhale valve 34 open, and then is discharged through theinner exhale cover 32 and theouter exhale cover 35. - However, in the conventional exhale part of the linear compressor, when the
loop pipe 36 is inserted into theouter exhale cover 35, it has difficulty in assembling anedge 38 of theloop pipe 36, while spaced apart from theinner exhale cover 32. - Furthermore, if the
loop pipe 36 is excessively inserted, theedge 38 of theloop pipe 36 may face theinner exhale cover 32. In this case, theedge 38 of theloop pipe 36 becomes clogged, and compressed fluid cannot be discharged through theloop pipe 36 to the outside. - Accordingly, it is an aspect of the present invention to provide a linear compressor having an inclined edge of a loop pipe, which prevents the loop pipe from clogging, and improves operation efficiency and reliability of the product.
- The foregoing and other aspects are achieved by providing the linear compressor based on the present invention, which comprises an exhale valve which opens and closes a cylinder, an inner exhale cover provided with an exhale hole which discharges fluid drained from the cylinder, an outer exhale cover positioned at a regular interval from an outer surface of the inner exhale cover, and the loop pipe inserted into the outer exhale cover to discharge fluid in the outer exhale cover to the outside.

- The loop pipe is rolled several times at a predetermined position within a hermetic casing.
- The inner exhale cover is provided with an exhale spring for elastically holding the exhale valve.
- The linear compressor, in accordance with the present invention comprises the hermetic casing, a linear motor equipped in the hermetic casing, a cylinder block set in the linear motor and provided with the cylinder, the piston which linearly reciprocates by the linear motor in the cylinder, and an exhale part located in a front of an opening of the cylinder to discharge fluid compressed in the cylinder. The exhale part includes the exhale valve that opens and closes the cylinder, the inner exhale cover having the exhale valve and the exhale hole that discharges fluid drained from the cylinder, the outer exhale cover placed at a regular interval from the outer surface of the inner exhale cover, and the loop pipe having the inclined edge inserted into the outer exhale cover to discharge fluid in the outer exhale cover to the outside.
- The outer exhale cover is equipped with the connection pipe to be connected to the loop pipe.
- The connection pipe is perpendicular to the direction of the piston in the outer exhale cover.

The embodiments are described below in order to explain the present invention by referring to the figures.
-
FIG. 3 shows a linear compressor, according to the present invention, andFIG. 4 shows a structure of an exhale part of the linear compressor, according to the present invention. - As referring to FIGS. 3 to 4, the linear compressor, in accordance with the present invention comprises a
hermetic casing 60, alinear motor 70 installed in thehermetic casing 60, acylinder block 62 set in thelinear motor 70 and provided with acylinder 61, apiston 63 set in thecylinder 61 to reciprocally move back and forth, by means of thelinear motor 70, and theexhale part 80 positioned in a front of an opening of thecylinder 61 to discharge fluid compressed in thecylinder 61. - The
cylinder block 62 is mounted in a front of thelinear motor 70, while aback cover 65 having aninlet 64 is mounted in a rear of thelinear motor 70. - The
linear motor 70 is divided by a stationary part and a movable part. The stationary part includes anouter core 71, aninner core 72, and acoil 73 with a magnetic field. The movable part includes amagnet 74 that linearly reciprocate by magnetic force around thecoil 73, and amagnetic frame 75 where themagnet 74 is fastened. - In one end of the
cylinder 61, thepiston 63 is inserted, and the other end is a cylindrical shape which is open at both sides, so as to discharge compressed fluid. Thepiston 63 and theexhale part 80 make a compression chamber C. - The
piston 63 is in a shape of a cylinder. In a front, aninlet 66 for inhaling fluid is placed, and aninhale valve 67 for opening and closing theinlet 66 is fixed by a connection member like a bolt. - The
piston 63 has aflange 68 in its rear, so as to be combined with themagnetic frame 75. As amain spring 76 is disposed between theflange 68 and thecylinder block 62, and asubsidiary spring 77 is disposed between theflange 68 and theback cover 65, so that thepiston 63 is elastically supported. - The
exhale part 80 includes anexhale valve 81 which opens and closes the opening of thecylinder 61, aninner exhale cover 83 provided with theexhale valve 81, an outer exhale cover 84 positioned at a regular interval from an outer surface of theinner exhale cover 83, and aloop pipe 85 inserted into the outer exhale cover 84 to discharge fluid in the outer exhale cover 84 to the outside. - The
exhale valve 81 is elastically held in the inner exhale cover 83 by anexhale spring 86. Theexhale spring 86 is a conic coil spring to give the elasticity toward a direction that theexhale valve 81 closes the compression chamber C of thecylinder 61. - An
exhale hole 82 is located in theinner exhale cover 83, so that fluid drained from the compression chamber C is discharged to the outer exhale cover 84. - The
exhale hole 82 is respectively formed in a front of theinner exhale cover 84 and its circumference. - The outer exhale cover 84 has a predetermined interval from the
inner exhale cover 83, apart from the outer surface of theinner exhale cover 83. - An
outlet 87 is perpendicular to a direction of thepiston 63 in the outer exhale cover 84, so as to discharge compressed fluid to the outside of the outer exhale cover 84. Theoutlet 87 has aconnection pipe 88 to be connected to theloop pipe 85. - The
loop pipe 85 is inserted into a space between the outer exhale cover 84 and the inner exhale cover 83 through theconnection pipe 88. In case that theloop pipe 85 is excessively inserted into the space between the outer exhale cover 84 and theinner exhale cover 83, at least one end of an edge of theloop pipe 85 is distant from the inner exhale cover 83 by predetermined distance. - The
loop pipe 85 has theinclined edge 89 inserted into the outer exhale cover 84. - The
loop pipe 85 is fixed by welding after being inserted into theconnection pipe 88. - The case that the
loop pipe 85 functions as a material by being rolled several times at a predetermined position or by being bended, in order to reduce a vibration and a noise occurring from discharging compressed fluid is explained as an example in the present invention, the loop pipe may have the material at a predetermined position. - A process of the linear compressor having the exhale part, according to the present invention is described in the following.
- When the
linear motor 70 is in operation, thepiston 63 linearly reciprocates within thecylinder 61. - When the
piston 63 moves forward, theexhale valve 81 becomes opened by the pressure of fluid compressed in thecylinder 61. Compressed fluid is discharged to the inside of theinner exhale cover 83. - Fluid discharged to the inner exhale cover 83 is discharged to the outer exhale cover 84 through the
exhale hole 82 in theinner exhale cover 83. - Fluid discharged to the space between the
inner exhale cover 83 and the outer exhale cover 84 is discharged to the outside through theloop pipe 85 connected to the outer exhale cover 84. - As the edge of the
loop pipe 85 is arranged between theinner exhale cover 83 and the outer exhale cover 84, compressed fluid can be discharged to the outside through theloop pipe 85. - Even though the
loop pipe 85 is excessively inserted into the outer exhale cover 84 through theconnection pipe 88, in assembling theloop pipe 85, as theedge 89 of theloop pipe 85 is inclined, only one end of theedge 89 of theloop pipe 85 is touched with theinner exhale cover 83, thus preventing theedge 89 of theloop pipe 85 from clogging. - As a result, fluid discharged to the outer exhale cover 84 from the
exhale hole 82 of the inner exhale cover 83 can be smoothly discharged to the outside after flowing into theedge 89 of theloop pipe 85. - The operational effects of the linear compressor, according to the present invention are described in the following.
- As apparent from the above description, the linear compressor of the present invention provides the inclined edge of the loop pipe, which is inserted into the outer exhale cover.
